WitrynaImines from Primary Amines – The Mechanism. There are two main parts in the net transformation; 1) nucleophilic addition of the primary amine and 2) elimination of H2O. All the steps are reversible, and the overall equilibrium of the reaction is shifted by removing H 2 O as we have also seen in the reaction of aldehydes and ketones with …
